Gene flow wikipedia
In population genetics, gene flow (also known as gene migration or geneflow and allele flow) is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and therefore can be considered a single effective … See more The level of gene flow among populations can be estimated by observing the dispersal of individuals and recording their reproductive success.

WebDec 19, 2016 · gene flow: [noun] the passage and establishment of genes typical of one breeding population into the gene pool of another. WebTools Allele frequency, or gene frequency, is the relative frequency of an allele (variant of a gene) at a particular locus in a population, expressed as a fraction or percentage. [1] Specifically, it is the fraction of all chromosomes in the population that carry that allele over the total population or sample size.
WebIn biology, a taxon ( back-formation from taxonomy; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. WebGene flow (migration) is the introduction of new individuals (and genes) into a target population. [7] Predicting the impact of a migrant on a population will depend on combination of complex genetic and non-genetic factors.
